tion with building openings such as windows and employing sliding sashes or other similar closures. I

The principal object of this invention is to provide a screen structure which can be automatically moved into position to cover a window opening when the sash is slid to open position. I

An additional object of the invention is to provide a structure of this character which can be normally housed within a compartment formed in one of the building walls adjacent one of the sides of the window or like frame. A further object of the invention is to provide a finishing strip for a screen. structure of this character which,

\ while normally housedwithin the screen sash compartment, is automatically moved outwardly to an operative position when the screen is shifted to an extended position.

Still another object of this invention is to provide a finishing strip of this character which together with its operating means can becompletely'carried by the screen sash. WVith these andv other objects inview, the invention resides in the novel features of construction, combination. and arrangement of parts. which will be hereinafter more par ticularly described and claimed..

In the accompanying drawings,

Figure 1 represents an elevational' view of a window frame and the adjacentparts of building ishowing the relation of my in .vention thereto. 5

, Fig.2 is an enlarged elevational view of certain parts shownin Fig. 11' and with other parts broken away and in section. i

Fig. 3is a horizontal seotionalvviewtaken substantially on the plane of the line'3-3 of Figs. 1 and 2 and,

Fig. 4 is a vertical sectional view onthe plane of the line 44 of Fig.1.

Referring more particularly to these drawings, the reference character 1 denotes a window frame having the usual sill 2 and sash grooves 3 in which upper and lower window sashes 4 and 5 respectively are vertically slidable. In carrying out the present invention, the building wall W below the sill 2 is provided with a screen sash compartment 6, ingress and egress for this compartment being had through a slot 7 formed in said sill 2. I 7

A screensash 8 is normally located within the compartment said sash consisting of a pair .cflike frames-9 between which a rectangle of screen material 10 is clamped. In other words the edges of the screen material are disposed between the two frames 9 which are then secured together by fastening elements such as the nuts and bolts '11. (For instance see Fig. 3). Together, the two frames 9 form a sash which is of a thickness substantially equal to thewidth of the slot 7 and corresponds to .thethickness of the lower window sash 5 as will be evident from Fig.4. M

Thus the screen sash 8 may readily slide in the sash grooves 3 of the window sash 5 as well as in grooves provided in the oppositewalls of the compartment 6. Inasmuch as it is desirable that the screen sash 8 be moved simultaneously withthe window sash 5, means is provided for detachably'connectlatch plate 14 on the sash 8. Even though the two sashes 5 and 8 arenormally moved vertically together, it is obvious that they may be individually slid to theirdifierent positions when the latch 12. is not in use.

Ordinarily the sash 5 is not raised to such an extent as to expose' the bottom ofthe screen sash 8, therefore apairof finishing strips 15 are provided for use when-the screen sash is raised, these finishing strips, when in operative position, beinglocated one on each side of. the screencovering 10 adjacent thesill 2. Thus'that portion of the screen covering 10 close to said sillis protected as would be-the'case if the screen sash was completely extended out of its compartment. When the screen sash is housed within the compartment 6, the finishing strips are likewise located therein, and under normal conditions are capable only of a limited outward movement, they being restrained by spring pre'sseddetents 16 which project from their opposite surfaces and engage the opposite 21, one of which is located at each upper corner of each of the frames 9, and connected with the counter-balance weights 17 *these weights being housed within channels 22 formed in the vertical sides of said frames 9.

In the use of the invention, assuming that it is desired to simultaneouslyraise the lower sash 5 and elevate the screen sash to close the resultant window opening the latch 12 is operated to connect the sashes 5 and 8:50- gether, whereupon as the former is raised to a predetermined extent, the screen sash is correspondingly raised. As soon as the upper side thereof is raised above :the sill 2, the finishing strips 15 will be extended outwardly of the compartment 6 until the detents 16 are engaged as shown in Fig. 4;, this raisingofthe strips being automatically accomplished by the counter-balance weights 17. Should it be necessary toentirely remove the screen sash 8 from the compartment 6, the finishing strips 15 are forcibly raised to retract the detents 16 and cause them to slide through the slot '7. On the downward movement of the window sash 5, the screen sash will be lowered to a similar extent, but the finishingstrips 15 will remain stationary until engaged by the upper side ofsaid sash'8. V

I claim: 7

1. The combination with a window or similar frame having an opening at one side providing an entrance waylinto a sash compartment, of a sash movable into and out of the compartment, and a movable finislr' ing strip extending across the sash in the side of the frame ad acentsa1d opening wherebyto simulatea portion of said sash.

2. The combination with a window or similar frame having an-opening at one side providing an entrance way into a sashcompartment, of a-sash movable into and out-of the compartment, a movable finishing strip extending across the sash, said strip being housed within said compartment whenthe sash is retracted, and means for moving the strip exteriorly of the i compartment 'to a position adjacent the opening thereof when the sash is positioned outwardly of its com-. partment.

3. The combination with a window or similar frame having an opening at one side providing an entrance way into a sash compartment, of a sash movable into and out of :the compartment, a movable finishing strip extending across the sash, said strip being housed within said compartment when the sash is retracted, means for moving the strip .exteriorly of the ,compartment when the sash is positioned outwardly of itscompartment, means normally limiting said outward movement of the strip to a position adjacent said opening in' the frame side, said limiting means being operable to permit further movement of the strip when it is desired to move the sash entirely from the frame.

4. The combination with a window or similar frame having an opening in one side providing an entrance way into a sash com partment, and a main sash movable in the frame, of an auxiliary sash movable into and out of the' compartment by -movement of the main sash, means for detachably-connecting'the two sashes together, and a finishing strip normally disposed in said compartment and movable outwardly thereof-to a position adjacent said opening in the frame side when the auxiliary sash moved outwardly v i 5. The combination with a window or similar rame having an opening in one side providing an entrance way into-a sash compartment, and a main sash movable in the frame, of an auxiliary sash movable into andout of the compartment by movement of the main sash, meansfor detachablyconnecting the two sashestogether, a finishing strip slidable in the frame of the auxiliary sash and normally disposed in said. compartment, and mean for moving the strip outwardly a limited extentwhen the aruiiliary sash is moved out'of the compartment.

'6. The combination with a window or similar frame having an opening in one side providing an entrance way into a sash compartment, and a main sash movable in the frame, of an auxiliary sash movable into and out of the compartment by movement of the main sash, means for detac'hably connecting the two sashes together, a finishing strip slidable in the frameof the auxiliary sash and normally disposed, in said compartment, and means "located in the auxi] y sash for moving the strip outwardly a" 11111- ited extent when the auxiliarysash is moved out of'the compartment.

In testimony that I elaim'the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of lVisconsin.
